traffic lost

I have cpa websites which i use to promote with youtube , my daily average hits are 500 to 1k everyday for each site , but today all the traffic is gone , all my videos are up still getting views but no conversions only few clicks in ogads , what could be the reason?

I tried mostly everything to fix it but cant fix. its making me a little depressed tbh , suddenly my earnings droped to 0 and i have no other option left to pay my bills

its been stable for like a year or so
please let me know any idea or suggestions you have from experiences

Think that ogads lost many good offers
